Stephane Smith 988827b85a esp32/modesp32: Properly define RTC_VALID_EXT_PINS on S2/S3 variants.
On ESP32 S2/S3 variants, GPIO0 through GPIO21 are valid RTC pins.  This
commit defines the valid RTC_VALID_EXT_PINS for the S2/S3 variants,
otherwise, it keeps functionality the same.

Stephane Smith 7005354099 esp32/machine_pin: Don't expose pins 33-37 when octal SPIRAM is enabled.
For ESP32-S3 configurations, CONFIG_SPIRAM_MODE_OCT requires pins 33-37 for
PSRAM.  So exclude them from the machine_pin_type and machine_pin_irq_type
object tables.

Stephane Smith ae3d5289a5 esp32/boards: Compile GENERIC_SPIRAM and UM_TINYPICO with -Os.
These boards do not build with IDF v4.4 because the section .iram0.text
does not fit in region iram0_0_seg.  Enabling SPIRAM increases the code
size so use -Os instead of -O2 to build these boards.

Fixes issue #8260.

Damien George fe9eaf12f3 esp32: Add MICROPY_HW_ENABLE_UART_REPL and enable on generic S2/S3.
Some S2/S3 modules don't use the native USB interface but instead have an
external USB-UART.  To make the GENERIC_S3/S3 firmware work on these boards
the UART REPL is enabled in addition to the native USB CDC REPL.

Peter Hinch d242a9b7f7 rp2/machine_uart: Use read/write mutex to prevent char duplication.
Duplication of characters is caused by re-entrant calls from separate cores
of uart_fill_tx_fifo().  This patch uses a mutex to ensure that a
re-entrant execution of the function returns without affecting the UART
FIFO.

Fixes issues #8344 and #8360.

Martin Fischer 5873390226 rp2/mphalport: Fix USB CDC RX handling to not block when unprocessed.
Prior to this commit, the USB CDC OUT endpoint got NACK'd if a character
was received but not consumed by the application, e.g. via
sys.stdin.read().  This meant that USB CDC was blocked and no additional
characters could be sent from the host.  In particular a ctrl-C could not
interrupt the application if another character was pending.

To fix the issue, the approach in this commit uses a callback tud_cdc_rx_cb
which is called by the TinyUSB stack on reception of new CDC data.  By
consuming the data immediately, the endpoint does not stall anymore.  The
previous handler tud_cdc_rx_wanted_cb was made obsolete and removed.

In addition some cleanup was done along the way: by adding interrupt_char.c
and removing the existing code mp_hal_set_interrupt_char().  Also, there is
now only one (stdin) ringbuffer.

Fixes issue #7996.

iabdalkader 5562ed3f43 stm32/pyb_can: Replace CAN.initfilterbanks with CAN.init keyword arg.
The CAN.initfilterbanks() class method is removed, and its functionality is
replaced with the "num_filter_banks" keyword argument to the CAN
constructor and CAN.init().  This configures the filter bank split.

This new approach provides more flexibility configuring the resources used
by a given CAN instance, allowing other MCUs like H7 to fit the API.  It
also brings CAN closer to how other machine peripherals are configured,
where everything is done in the constructor/init method.

This is a breaking change to the CAN API.

iabdalkader e7264e9532 stm32/pyb_can: Add support for bus with mixed Classic/FD nodes.
A CAN bus can have mixed classic/FD nodes.  Prior to this patch the CAN API
could be configured for either standard or extended ID, but not both/mixed
operation.

This patch allows extended IDs to be filtered and enabled on a per-message
basis, in send(), setfilter() and clearfilter().

This is a breaking change to the API: init() no longer accepts the extframe
keyword argument.

it does.

This commit removes PULL_HOLD and adds a new hold=True|False keyword
argument to Pin()/Pin.init().  Setting this to True will cause the ESP32 to
lock the configuration of the pin – including direction, output value,
drive strength, pull-up/-down – such that it can't be accidentally changed
and will be retained through a watchdog or internal reset.

Daniël van de Giessen 665f0e2a68 esp32: Sleep one tick in MICROPY_EVENT_POLL_HOOK.
If MicroPython threads are enabled, loops waiting for an incoming event
should release the GIL and suspend, allowing other tasks to run while they
wait.

Prior to this commit, the problem can easily be observed by running a
thread that is both busy and regularly releases the GIL (for example a loop
doing something then sleeping a few ms after each iteration).  When the
main task is at the REPL, the thread is significantly stalled.  If the main
task is manually made to release the GIL (for example, by calling
utime.sleep_ms(500)) the other thread can be seen immediately working at
the expected speed again.

Additionally, there are various instances in where blocking functions run
MICROPY_EVENT_POLL_HOOK in a loop while they wait for a certain event/
condition.  For example the uselect methods poll objects to determine
whether data is available, but uses 100% of CPU while it does, constantly
calling MICROPY_EVENT_POLL_HOOK in the process.

The MICROPY_EVENT_POLL_HOOK macro is only ever used in waiting loops, where
(if threads are enabled) it makes sense to yield for a single tick so that
these loops do not consume all CPU cycles but instead other threads may
execute.  (In fact, the thing these loops wait for may even indirectly or
directly depend on another task being able to run.)

This change moves the sleep that was inside the REPL input function to
inside the MICROPY_EVENT_POLL_HOOK macro, where the GIL is already being
released, solving both the blocking REPL issue and the 100% CPU use issue
at the same time.

Damien George f2040bfc7e py: Rework bytecode and .mpy file format to be mostly static data.
Background: .mpy files are precompiled .py files, built using mpy-cross,
that contain compiled bytecode functions (and can also contain machine
code). The benefit of using an .mpy file over a .py file is that they are
faster to import and take less memory when importing.  They are also
smaller on disk.

But the real benefit of .mpy files comes when they are frozen into the
firmware.  This is done by loading the .mpy file during compilation of the
firmware and turning it into a set of big C data structures (the job of
mpy-tool.py), which are then compiled and downloaded into the ROM of a
device.  These C data structures can be executed in-place, ie directly from
ROM.  This makes importing even faster because there is very little to do,
and also means such frozen modules take up much less RAM (because their
bytecode stays in ROM).

The downside of frozen code is that it requires recompiling and reflashing
the entire firmware.  This can be a big barrier to entry, slows down
development time, and makes it harder to do OTA updates of frozen code
(because the whole firmware must be updated).

This commit attempts to solve this problem by providing a solution that
sits between loading .mpy files into RAM and freezing them into the
firmware.  The .mpy file format has been reworked so that it consists of
data and bytecode which is mostly static and ready to run in-place.  If
these new .mpy files are located in flash/ROM which is memory addressable,
the .mpy file can be executed (mostly) in-place.

With this approach there is still a small amount of unpacking and linking
of the .mpy file that needs to be done when it's imported, but it's still
much better than loading an .mpy from disk into RAM (although not as good
as freezing .mpy files into the firmware).

The main trick to make static .mpy files is to adjust the bytecode so any
qstrs that it references now go through a lookup table to convert from
local qstr number in the module to global qstr number in the firmware.
That means the bytecode does not need linking/rewriting of qstrs when it's
loaded.  Instead only a small qstr table needs to be built (and put in RAM)
at import time.  This means the bytecode itself is static/constant and can
be used directly if it's in addressable memory.  Also the qstr string data
in the .mpy file, and some constant object data, can be used directly.
Note that the qstr table is global to the module (ie not per function).

In more detail, in the VM what used to be (schematically):

    qst = DECODE_QSTR_VALUE;

is now (schematically):

    idx = DECODE_QSTR_INDEX;
    qst = qstr_table[idx];

That allows the bytecode to be fixed at compile time and not need
relinking/rewriting of the qstr values.  Only qstr_table needs to be linked
when the .mpy is loaded.

Incidentally, this helps to reduce the size of bytecode because what used
to be 2-byte qstr values in the bytecode are now (mostly) 1-byte indices.
If the module uses the same qstr more than two times then the bytecode is
smaller than before.

The following changes are measured for this commit compared to the
previous (the baseline):
- average 7%-9% reduction in size of .mpy files
- frozen code size is reduced by about 5%-7%
- importing .py files uses about 5% less RAM in total
- importing .mpy files uses about 4% less RAM in total
- importing .py and .mpy files takes about the same time as before

The qstr indirection in the bytecode has only a small impact on VM
performance.  For stm32 on PYBv1.0 the performance change of this commit
is:

As part of this change the .mpy file format version is bumped to version 6.
And mpy-tool.py has been improved to provide a good visualisation of the
contents of .mpy files.

In summary: this commit changes the bytecode to use qstr indirection, and
reworks the .mpy file format to be simpler and allow .mpy files to be
executed in-place.  Performance is not impacted too much.  Eventually it
will be possible to store such .mpy files in a linear, read-only, memory-
mappable filesystem so they can be executed from flash/ROM.  This will
essentially be able to replace frozen code for most applications.

YoungJoon Chun d8a7bf83cc rp2/machine_uart: Fix UART RTS behaviour so RTS is deasserted.
The UART hardware flow control was not working correctly, the receive FIFO
was always fetched and RTS was never deasserted.  This is not a problem
when hardware flow control is not used: normally, if the receive FIFO is
full, the UART receiver won't receive data into the FIFO anymore, but the
current implementation fetches from the FIFO and discards it instead.
The problem is that data is discarded even when RTS is enabled.

This commit fixes the issue by only taking from the FIFO if there is room
in the ring buffer to put the character.

This also fixes a possible race condition when exiting initialisation mode:
reading then writing to ISR (via ISR &= ~RTC_ISR_INIT) will clear any flags
that were set by the hardware between the read and the write.  The correct
way to clear just the INIT bit is to just do a single write via ISR =
~RTC_ISR_INIT, which will not clear any other flags (they must be written
to 0 to clear), and that is exactly what LL_RTC_DisableInitMode does.

Herwin Grobben 160e4d9a6d stm32/fdcan: Fix FIFO1 usage and handling of error interrupts.
The original code used a independent state with regards to the interrupt.
During heavy bus error conditions the internal state could become
out-of-sync with the interrupts.

Further explanation: during the development of an application using CAN
communication, a interrupt-run-away was found in some situations.  It was
found that the error interrupt triggered (Warning, Passive or Bus-Off, all
triggered it) the run-away.  The only recovery was a reset.

Two problems were found:
- the error interrupt is enabled but not cleared in the interrupt routine;
- an internal variable 'State' that was used to track the message received
  state (empty, new, full, overflow) that was not directly related to
  interrupt that indicated the state.

In this commit these issues are fixed by adding more values for the
interrupt reason (warning, passive, bus off) and clearing the error
interrupts, and making the internal state directly dependent on the
interrupt state for received messages.

Furthermore, introducing the FIFO1 in the CAN receive stage, another issue
existed.  Even if the messages are received into the FIFO1 (by selecting
message filtering for FIFO0 and FIFO1), the interrupt firing was indicating
FIFO0 Rx.  The configuration of the interrupts for this is now also fixed.
The CAN peripheral has 2 interrupt lines going into the NVIC controller.
The assignment of the interrupt reasons to these 2 interrupt lines was
missing.  Now the reception of FIFO1 messages triggers the second interrupt
line.  Other interrupts (Rx FIFO0 and bus error) are assigned to the first
interrupt line.

Tested on a Nucleo-G474, and also checked the HAL function to work with the
H7 family.

Damien George 608d421752 stm32/mboot: Remove custom HAL_RCC_GetHCLKFreq and use HAL provided one.
So that a board can access other HAL_RCC functions if it needs them (this
was not possible previously by just adding hal_rcc.c to the src list for a
board because it would clash with the custom HAL_RCC_GetHCLKFreq function).

Damien George 5e506567a3 stm32/mbedtls: Enable MBEDTLS_TLS_DEFAULT_ALLOW_SHA1_IN_KEY_EXCHANGE.
This adds MBEDTLS_MD_SHA1 to the list of default hashes for TLS 1.2
handshake signatures.  Although SHA-1 is weak, this option is turned on in
the default mbedtls configuration file, and allows better compatibility
with older servers.  In particular it allows an stm32-mbedtls-based client
to connect to an axtls-based client (eg default unix port and esp8266).

Damien George a3bbd5332b esp32/machine_bitstream: Reinstate bitstream bit-bang implementation.
The bit-bang implementation was replaced with the RMT implementation in
599b61c086.  This commit brings back that
bit-bang code, and allows it to be selected via the new static method:

    esp32.RMT.bitstream_channel(None)

The bit-bang implementation may be useful if the RMT needs to be used for
something else, or if bit-banging is more stable in certain applications.

Damien George e754c2e84f esp32/esp32_rmt: Install RMT driver on core 1.
MicroPython currently runs on core 0 of the esp32.  Calling
rmt_driver_install will mean that the RMT interrupt handler is also
serviced on core 0.  This can lead to glitches in the RMT output if
WiFi is enabled (for esp32.RMT and machine.bitstream).

This patch calls rmt_driver_install on core 1, ensuring that the RMT
interrupt handler is serviced on core 1.  This prevents glitches.

Fixes issue #8161.
